The first Ardrossan Castle Carnival was held on 18 June 2016 to commemorate
the meeting of the Privy Council in Ardrossan exactly 470 years earlier on 18
June 1546. The Privy Council was the equivalent of the Cabinet of the Scottish
Government. The meeting was chaired by Lord James Hamilton, regent to the four-year-old
Mary, Queen of Scots, and effective King of Scotland. The celebration was hosted
by Ardrossan Castle Heritage Society.
